primitive antique farm tool hand grinder for sharpening knives & tools

Old primitive hand crank grinding wheel from an old farm estate. This grinder would clamp a work bench or the kitchen table for sharpening tools, scissors, knives around the farm. This has a wood handle on the hand crank. The grinding wheel is aluminum-oxide and measures about 4 inches across.

This grinder is in good running condition with soil and grease from years in the farm shop.
